METHOD OF WRAZPIE'ING FOLDING PASTEBOAED BOXES.

Application filed October 23, 1920.

To all whom it may concern:

Be it known that I, HERBERT H. WAGNER, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and useful Method of Wrapping Folding Pasteboard Boxes, of which the following is a specification.

This invention relates to a process of unlting a paper wrapper with a pasteboard folding box of the one-piece type.

The general object of the invention is to so unite a paper wrapper with a folding box having a hinge section that the paper will not tear along the hinge lines when the box is folded.

The specific object of the invention is the provision of a method of uniting the paste board box described and claimed in an a plication filed October 7, 1920, Serial 0. 5,413, with a paper wrapper descrlbed and claimed in a second application filed of even date herewith, Serial No. 418,881. The means employed for carrying out the present process is the subject of a fourth appllcatlon of even date herewith, Serial No. 418,883.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understandmg, however, that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modifled so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appendedclaims.

Serial No. 418,882.

The numeral 10 designates the receptacle 7' portion of the box, and 11 the cover portion, the two being united together by an intermediate hinge portion. The receptacle portion has side flanges 13 and an end flange 15, each side flange having integral tabs 14. The cover portion has side flanges 16 and an end flange 17. Binding means 18 holds the abutted edges of the flanges of the cover and receptacle portions of the box together.

The wrapper 19 has four reentrant cuts 20 providing end flaps or flanges 21 and has opposite cuts 22 intermediate the cuts 20, which cuts 22 are joined with slits 23 extending farther into the material of the cover and provided with branch slits 24:,

or flaps 26 are defined by the slits 23and 24c, and the cuts 22 and 20. As will be understood from Figs. 1 and 2 of the drawing, the end flanges 21 are designed to fit against and be secured to the corresponding flanges 15 and 17 of the box; the flanges 26 are designed to be united to the flanges 13 of the box; and the flanges 27 are designed to fit over the flanges 16 of the box. The tabs 28 are opposite each other, as stated, and the portion of the wrapper lying between said tabs is designed to fit over the outside of the hinge portion 12 of the box. The tabs 14: are free from the hinge portion of the box by the provision of a V-shaped cut and are also spaced from the ends of the flanges 16 of the cover portion. The tabs 28 have approximately the width of the hinge portion and are adapted to be united to the inside face of said hinge portion. The

tabs 23 are to be secured to the inner wall of each flange 16 at the end thereof adja cent the hinge portion of the box. Each of the flanges of the wrapper hassuflicient 5 width to not only completely cover the outer walls of the corresponding flanges of the box but to be received inside of the box and to be united with the inside walls of all the flanges so that the edges of said flanges are completely covered.

The hinge portion of the box is integral with the remainder of the box and is defined by two crease lines 25, said crease lines being formed parallel to each other and be ing made by a blunt instrument which compresses the material of the box but does not cut the fibers thereof. These crease lines, therefore, do not weaken the box along the hinge lines. The box is slightly tapered from the cover end to the receptacle end so that the cover with its flanges may inclose the receptacle after the box is folded. This folding of the box will be understood from Fig. 7. The paper wrapper may likewise have a slight taper so as to accommodate itself to the corresponding shape of the box.

The first step of the present process consists in coating the wrapper on one side with mucilage or other adhesive material. Then the box, in the condition illustrated in Fig.

l, is placed upon a form, said form fitting the interior of the box and holding the upstanding flanges of the box so that crushing of-the box is prevented. Then this form descends into a wrapping machine whereby the box is thrust down against the coated side of thewrapper.- A block provides an anvil against which the upper moving form may press, this block being indicated at 29 in F ig.3. The upper face of the block has felt pads 80, said pads being substantially rectangular and spaced apart as indicated at 31. This break in the pads has a very important result. The wrapper is unitedfirst to the outer faces of the receptacle portions 10 and 11 of the box. It is not united to the hinge portion 12 of the box; and in fact, in order to clearly indicate the separateness of the wrapper and box at this stage of the process. the wrapper is shown with the part 32 in Figs. 3', 5 and 6. The part 32 here bridges thehinge portion between the crease lines 25 and, in an exaggerated way, brings out the fact that no portion of the wrapper ,between the felt pads 30 stir-ks to the box.

After the main body of the wrapper has been'united to the main body of the box. the

wrapping machine operates rollers which pass up along the sides of the box and afterward operates other rollers which move upwardly against the ends of the box. The action of these rollers is to press the flanges of the'wrapper against the corresponding portions of the box, whereupon the wrapper will stand up in the position illustrated in Fig. 3. Thenthewrapping machine operates to fold the free edges or the wrapper inside of the box so that the edges of the box are all well covered. The folded-in edges of the wrapper are shown in Fig. 5. In this condition, the box comes from the wrapping machine. The operator will press the tabs down against the inside wall of the hinge portion of the box, as seen in Fig. 6, and also will fold the tabs 23 in position, besides bendii'ig in the tabs 14 of the box. The wrapping of the box is now complete except that the part 32 of the wrapper is still free of the hinge portion. This last step in the uniting of the wrapper is effected by folding the box along the two crease lines 25, whereupon the part 32 of the wrapper is stretched and laid against the hinge portion and the adhesive on the wrapper makes it adhere to the box throughout.

It has been found that if the entire wrapper is united to the box when the form carrying the box descends into the wrapping machine, the paper will ultimately split along the hinge lines, thus making the box unsightly and not readily marketable. In order to eliminate this highly undesirable breaking of the paper, a separate uniting of the wrapper with the hinge portion of the box after all the other steps of the wrapping have taken place is absolutely essential. A. box of the character described is particularly suscepible to breakage of the paper wrapper because of the employment of two hinge lines, the box being a foldable one. Boxes made by the present process will not only show no breaks in the paper wrapper, but will not break along the hinge lines due to the employment of the creases in place of score lines; thus they are more serviceable 1 than ordinary boxes. It may be further stated that boxes of the folding type may be made twice as rapidly as two-part set-up boxes and represent a considerable saving in material and laborover such boxes. 7 What is claimed is p- 1. The process of uniting wrappers to boxes pf the folding type, said boxes each comprlsing a receptacle portion, a cover portion, and a hinge portion joining the other two portions, which consists in coating one face of said wrapper with an adhe-- sive, placing the box over and forcing the box against the wrapper, supporting the wrapper so that it is united only by said box no movement to the cover and. receptacle portions with the hinge portion left free of the wrapper, and folding the cover portion over to inclose the receptacle portion whereby the wrapper portion previously disunited to the outer face of the hinge portion is stretched upon and laid flat against said face and united thereto.

2. The process of uniting wrappers to I boxes of the folding type, said boxes each comprising a receptacle portion, a cover portion, and a hinge portion joining the other two portions, which consists in coating one face of said wrapper with an adhesive, placing the box over and forcing the box against said wrapper, supporting the wrapper so that it is united by said box movement only to the cover and receptacle portions with the hinge portion left free of the wrapper, uniting portions of said wrapper to the inner wall or face of the hinge portion, and folding the cover portion over to inclose the receptacle portion whereby the wrapper portion previously disunited to the outer face of the hinge portion is stretched upon and laid flat against the said face and united thereto.

5. The process of uniting wrappers to boxes of the folding type, said boxes each comprising a receptacle portion, a cover portion, and a hinge portion uniting the other two portions, the receptacle and cover portions each having side and end flanges, the wrapper having corresponding flanges, which consists in coating one face of said wrapper with an adhesive, placing the box over and forcing it against said wrapper, supporting the wrapper so that it is united by said box movement only to the cover and receptacle portions, with the hinge portion left free of the wrapper, uniting the flanges of the wrapper to both the inside and outside faces of the corresponding flanges of the box, uniting portions of said wrapper to the interior wall or face of the hinge portion, and folding the cover portion over to inclose the receptacle whereby the part of the wrapper previously disunited to the outer face of the hinge portion is stretched upon and laid flat against said face and united thereto.

The process of uniting wrappers to boxes of the folding type, said boxes each comprising a receptacle portion, a cover portion, and a hinge portion joining the other two portions, said receptacle and cover portions both having side and end flanges, the side flanges of the receptacle portion having tabs, said wrapper having flanges corresponding with the flanges of the box and also having tabs at opposite points, which consists in coating one face of said wrapper with adhesive, forcing the box against the coated face of the wrapper, supporting the wrapper so that it is united by said box movement only to the cover and receptacle portions with the hinge portion left free of the wrapper, uniting the flanges of the wrapper with the corresponding flanges of the box to both the inner and outer faces thereof, bending the tabs of the box inwardly, uniting opposite tabs of the wrapper to the inner face of the hinge portion of the box, uniting other opposite tabs of the wrapper to the interior faces of the flanges of the cover portion of the box, and folding the cover portion over to inclose the receptacle portion whereby the wrapper portion previously left disunited to the outer face of the hinge portion is stretched upon and laid flat against said face and united thereto.

5. The process of wrapping folding paper boxes of that type consisting of a receptacle portion, a cover portion and a hinge portion joining the receptacle and cover portions, said hinge portion being defined by two parallel crease lines, which consists in coating with an adhesive one face of said wrapper, placing the box upon the wrapper, forcing the box and wrapper together except at the hinge portion so that the wrapper and box may be united, and then folding the cover portion upon the receptacle portion and at the same time uniting the wrapper to the box at the hinge portion.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

HERBERT H. WAGNER.
